Title: Ultrasonic probe
Inventor: ITO TOSHIO
IPC: A61B8/00
Filed: 1989-02-01
Abstract: PURPOSE:To prevent the conduction of heat to a diagnostic portion of a detected body and prevent a feeling of physical disorder to a patient by transmitting a heat generated from a vibrator from an intermediate connecting part to a heat releasing plate, and releasing the heat to the opposite side to the ultrasonic wave radiating surface. CONSTITUTION:An intermediate connecting part 26 formed of a heat releasing resin having a satisfactory heat conductivity is adhered to the side surface outer circumferential part of a vibrating plate to, a heat releasing plate 28 having a satisfactory heat conductivity is fitted to one end thereof, and the other end of the heat releasing plate 28 is fixed to a shield plate 22 disposed on the inner wall of a case. At the time of bringing a probe into contact with the affected part of a living body which is a detected body and making a diagnosis, a heat is, if generated from the vibrator 10, transmitted to the intermediate connecting part 26, further propagated to the heat releasing plate 28 consisting of high heat conductive materials, and transmitted from the shield plate 22 to the rear of the case. Consequently, the heat generated from the vibrator 10 can be released to the opposite side to the ultrasonic radiating surface. Thus, the heat is never conducted from the contacted probe to the detected body affected part, and a feeling of physical disorder by heat of the patient and a low temperature burn can be certainly prevented.
